- Compare services on price, BAS, Xero and lock-in, not the headline price alone.
- Fixed-fee services run from about $275 to $499 a month and suit most small businesses.

If you’re comparing online bookkeeping services Australia-wide, the hard part isn’t the bookkeeping. It’s working out which provider actually fits your business, because they price and package the work very differently. This guide lines up the main options side by side, including Sleek’s online bookkeeping service, so you can see who suits whom on the things that decide the bill.
We compare price, whether BAS is included, which software they run in, and how much is locked in, then give you a short “choose this one if…” list so you can make the call. Every price below was checked on each provider’s own site in October 2026, and we’ve said plainly where each one genuinely wins, even where that isn’t Sleek.
How should a small Australian business choose a bookkeeping service?
Start with the model, then the provider. Most Australian small businesses are best served by an online fixed-fee service that works in Xero and includes BAS, because the cost is predictable and the work is genuinely off your plate. Sole traders with simple finances can often use a lighter pay-as-you-go option, while businesses that also want tax and advice may prefer a service that bundles bookkeeping with an accountant.
Whichever way you lean, compare every option on the same four things: price and what the fee includes, BAS handling, whether it’s Xero-native, and whether you’re locked into a contract. Those four decide the real cost far more than the headline monthly number.
What are the four ways to handle bookkeeping in Australia?
Before comparing providers, it helps to know the four realistic paths. Most of the services below sit in the third one.
- DIY in software. You run Xero, MYOB or an all-in-one app like Thriday yourself. Cheapest in dollars, most expensive in your time. Best for a pre-revenue sole trader with a handful of transactions.
- A local or freelance bookkeeper. Hands-on and personal, usually billed hourly. Good if you want someone nearby who knows your business face to face.
- An online fixed-fee service. Your books are handled remotely in Xero for a set monthly price, usually with BAS included. Built for owners who want it done without surprises.
- A full accounting firm. Bookkeeping bundled with tax, advisory and year-end work. Best when your accounts are complex or you want one firm across everything.
Location barely matters once the work happens in Xero. A cafe hunting for bookkeeping services in Sydney has the same options as a regional tradie or an online store, so pick the model that fits first, then compare the providers below.

How much do online bookkeeping services cost in Australia?
Online fixed-fee bookkeeping generally starts around $275 a month and runs to roughly $500 or more for fuller service, depending on your transaction volume and whether BAS is included. Sleek’s plans start from $275 a month, GST inclusive, with BAS handled, and you can review its fixed-fee pricing in full. POP Business lists bookkeeping from $499 a month. Independent 2026 data puts fixed monthly bookkeeping packages at $250 to $1,500 and hourly bookkeepers at $45 to $120 an hour, with payroll and BAS pushing the top end higher.
The sole-trader route is priced differently: Hnry charges 1% plus GST on each payment you receive, capped at $1,500 plus GST a year, with no subscription. Whichever you compare, always check the provider’s live pricing page before you buy, because rates change and most depend on your transaction volume. One question matters most: is BAS included? That single line moves the real cost more than the headline number.
Fixed-fee vs hourly: which pricing model is right for you?
Fixed-fee pricing gives you one predictable number each month, no matter how many questions you ask. Hourly billing can be cheaper when your books are tiny, but it quietly penalises you for needing help. For most growing businesses, predictable beats cheap.
If budgeting certainty matters to you, a fixed-fee bookkeeping package will suit you better than an open-ended hourly deal. If you only need a few hours a quarter and rarely have questions, hourly can still make sense. Match the model to how much support you actually use.
Do I need a bookkeeper if I already use Xero?
Using Xero and having your bookkeeping done are two different things. Xero is the tool; someone still has to reconcile accounts, chase coding errors, and keep it accurate for BAS. Plenty of owners have a tidy-looking Xero file that quietly drifts out of line.
If you’d rather not spend your evenings in the reconciliation screen, an online service that plugs into your existing Xero is the simplest fix. You keep your Xero, they keep the books right. That’s what most owners searching for bookkeeping services in Australia actually want.
Bookkeeper vs accountant vs BAS agent: who does what?
A bookkeeper keeps your day-to-day records accurate: invoices, bills, bank reconciliation, payroll data. An accountant uses those records for tax returns, year-end accounts and advice. A registered BAS agent is specifically authorised to prepare and lodge your BAS on your behalf.
- Bookkeeper: the ongoing record-keeping that keeps everything else reliable.
- Accountant: tax, compliance and strategy built on top of clean books.
- BAS agent: the person legally able to lodge your BAS on your behalf.
Good services roll these together, so always ask who is doing what, and if a provider will lodge your BAS, confirm they’re a registered BAS agent. If you also want tax and advice handled, a small business accountant can cover the bookkeeping and the year-end in one relationship.
How do you switch bookkeepers without disrupting your books?
Switching is the fear that keeps owners stuck with a provider they’ve outgrown, and it’s a common worry we hear from Australian businesses. In practice a clean handover is routine, and a good incoming service does most of the lifting for you.
- Confirm who owns your Xero file (it should be you, not the old provider).
- Give your new bookkeeper access, then revoke the old one once it’s confirmed.
- Agree a cut-over date so nothing is reconciled twice or missed.
- Check the last BAS period is closed off before the switch.
For a fuller walk-through, read our guide on how to switch accountants. The same steps apply whether you’re moving bookkeepers, accountants, or both at once.
What are the best bookkeeping options for sole traders?
Sole traders and freelancers have the simplest finances and the least time, so the maths is different. A pay-as-you-go service like Hnry can suit a one-person business that just wants tax and GST handled, while a cheaper fixed-fee tier makes sense once you’re reconciling regularly in Xero.
If your income is straightforward and you’re disciplined, DIY in software is a fair starting point. The moment bookkeeping starts eating billable hours, outsourcing it pays for itself in time alone. Our take on that jump is in do I need a bookkeeper as a sole trader, and if your tax is simple you can pair it with sole trader accounting. If you’re unsure whether to set up on a cash or accrual basis, our explainer on cash vs accrual accounting is worth five minutes.
How does Sleek’s fixed-fee bookkeeping service work?
Sleek is one of the fixed-fee services compared above. Your books are handled in Xero for a set monthly price from $275, BAS is taken care of, and you get a dedicated bookkeeper rather than a rotating queue, with a 30-day money-back guarantee and no lock-in contract. It suits owners who want the work gone, not managed, and who’d rather hand over reconciliations and BAS than spend evenings on them.
Where a hands-on local bookkeeper or a specialist like Bean Ninjas fits you better, this won’t be the pick, and that’s fine. The comparison above is there to help you decide honestly. If fixed-fee, Xero-native books with BAS included sound right, you can browse more in the Sleek AU knowledge base or get a quote.

FAQs on online bookkeeping services australia
Which is the best online bookkeeping service in Australia?
There’s no single best; it depends on your business. Fixed-fee services like Sleek and POP Business suit small businesses that want predictable monthly books with BAS; Bean Ninjas suits ecommerce; Hnry suits sole traders who want tax handled pay-as-you-go. Compare them on price, BAS inclusion, platform and lock-in rather than price alone.
How much do bookkeeping services cost for a small business in Australia?
Online fixed-fee bookkeeping starts around $275 a month and runs to $500 or more for fuller service, while local bookkeepers charge roughly $45 to $120 an hour or $250 to $1,500 a month. Always confirm whether BAS lodgement is included before comparing headline prices, and check each provider’s live pricing page, as rates depend on your transaction volume.
What's the difference between a bookkeeper and an accountant?
A bookkeeper keeps your day-to-day financial records accurate and up to date. An accountant uses those records for tax returns, year-end accounts and strategic advice. Many businesses use both, and some services combine the two under one roof.
Can a bookkeeping service lodge my BAS?
Only a registered BAS agent is authorised to prepare and lodge your BAS on your behalf. Many bookkeeping services employ or partner with registered BAS agents, so ask providers to confirm their registration number against the Tax Practitioners Board register before they lodge anything for you.
How do I switch bookkeepers without losing my records?
Make sure you own your Xero file, grant your new provider access, then revoke the old one once the handover is confirmed. Agree a cut-over date so no period is reconciled twice or missed. A good incoming service manages most of this for you.
Do sole traders and freelancers need a bookkeeping service?
Not always, but it often pays for itself once bookkeeping starts eating into billable time. Simple, disciplined sole traders can manage with DIY software, while a pay-as-you-go option like Hnry handles tax and GST without a monthly fee once the admin gets in the way.
